Winslow, Rte. 2, Box 229, Waukesha, Wis. Filed Mar. 15, 1963, Ser.No. 265,437 7 Claims. (Cl. 139-195) This invention relates to fireextinguishers and has particular relation to a hand-held extinguisher.

One purpose of the invention is to provide a compact, readily accessibleextinguisher employing water as an extinguishing agent.

Another purpose is to provide an extinguisher of maximum compactnesswhich may nonetheless be employed at points remote from the source ofextinguishing fluid.

Another purpose is to provide a hand fire extinguisher of maximumeconomy in manufacture.

Another purpose is to provide an attractively-packaged extinguisher.

Another purpose is to provide a hand fire extinguisher which may beconnected to household sources of extinguishing fluid, such as water.

Other purposes will appear from time to time during the course of thespecification and claims.

The invention is illustrated more or less diagrammatically in theaccompanying drawings wherein:

FIGURE 1 is a side elevation;

FIGURE 2 is a side elevation in partial cross section and on an enlargedscale; and

FIGURE 3 is a side elevation on the scale of FIG- URE l and illustratingthe invention in use.

Like parts are indicated by like numerals throughout the specificationand drawings.

Referring now to the drawings, and particularly to FIGURE 1, the numeral1 designates a housing. The housing 1 has a main housing portion 2 and anozzle cap 3.

As may be best seen in FIGURE 2, the portion 1 has an upper frustoconical portion 4 with an open, outwardly threaded upper end portion 5.The cap 3 has an inwardly threaded open bottom end indicated at 6 forengagement with the threaded portion 5. The nozzle cap 3, also generallyfrusto-conical, has a central continuing nozzle end portion 7 throughwhich the reduced nozzle passage or orifice 8 extendsfor communicationwith the chamber area A within housing 1.

A hose fitting 9 has agenerally circular flange 10 clamped between cap 3and housing portion 5. A bushing 11 extends inwardly of housing portion4 from the flange 10 and a passage 12 extends axially through bushing 11for communication with chamber A. Secured to the bushing 11 forcommunication with the passage 12 is an elongated flexible hose 13. Thehose 13 is folded in a plurality of convolutions within the housingportion 4.

The housing 1 has a lower generally frusto-c-onical portion 15 with alower open end 16 in which a snap fitting 17 engages. The fitting 17 iscarried by a connector 18 to which the lower end of hose 13 is secured,as indicated generally at 19. The hose 13 may be secured to the neck ofconnector 18 by a wire clamp 20, the opposite end of hose 13 beingsecured to bushing 11 by a similar wire clamp 21.

While the structure of the invention may be formed of a variety ofmaterials without departing from the nature and scope of the invention,it has been found convenient to form the housing 1, cap 3 and fitting 9of plastic material. Similarly, the hose 13 may be formed of relativelythin plastic to provide for a maximum length of hose folded in agenerally flat cross-sectional configuration within the housing 1. Theconnector 18 may conveniently be formed of rubberlike material. Thedevice of the invention thus formed is light in weight and economical inmanufacture.

Referring now to FIGURE 3, the connector 18 is shown as frictionallyengaged with the outlet end of a faucet 25. The housing 1 has beensnapped out of engagement with the fitting 17 and a major portion of thehose 13 has been drawn out of the housing 1. With water emanating fromfaucet 25, the same passes through the hose 13 into the chamber Abetween fitting 9 and outlet nozzle 7 from whence the fluid passesthrough the restricted nozzle orifice 8 for direction upon the fire. Thehousing 1 is held in the users hand. By employing a hose of relativelythin plastic material it has been found possible to fit within a housing1 of approximately. 5 inches in length and 2 inches at its majordiameter a hose approximating 25 feet in length. A hose of such thinplastic may be flattened into ribbonlike form for folding within thehousing 1 and may yet expand into tubular form, as illustrated in FIGURE3, upon the flow of fluid therethrough.

After use, the connector fitting 18 is simply removed from outlet 25,the hose 13 is drained of any remaining fluid therein and the hose 13 isfolded upon itself within housing 1 as indicated in FIGURE 2. When thehose 13 has been fully folded within housing 1, the fitting 17, carriedby the connector 18, is then strapped into place within the lower openend of housing portion 15 and the extinguisher is ready for use, theconnector 18 serving as a suitable stand for the extinguisher at aconvenient point adjacent a suitable water outlet. Thus is provided auseful kitchen accessory, for example. Should a fire occur which isextinguishable by the employment of water, it is only necessary that theuser snap the connector 18 into engagement with the readily availablekitchen faucet, grasp the housing 1 and pull it from the fitting 17 andmove the extinguisher to the location of the fire. With the water turnedon at the faucet a spray of water will be forcibly delivered from theorifice 8 onto the fire. While reference is made to a kitchen accessory,it will be understood that the Structure of the invention may beemployed at a variety of locations wherever a water outlet may be found.

The structure of the invention provides an attractive appearing,extremely compact appearance, requiring a minimum employment of space instorage and sufiiciently attractive to be stored in the open where itremains readily available at hand. Employment of fitting 9 and removablecap 3 provides a plenum chamebr A and permits of ease in disassembly andcleaning.

Whereas there has been shown and described an operative form of theinvention, it should be understood that this showing and description areto be taken in an illustrative or diagrammatic sense only. There aremany modifications in and to the invention which will be apparent tothose skilled in the art and which will fall within the scope and spiritof the invention. The scope of the invention should, therefore, belimited only by the scope of the hereinafter appended claims.
